The Spread Eagle is on Northcourt Road, which runs between the Oxford Road and Wootton Road in North Abingdon. It is about 200m from the Oxford Road.
You will find Northcourt Road on the Oxford road opposite another pub, The Boundary House. Also here are the bus stops for the fast bus links to Oxford (X3, X13, every 10 minutes to/from the city centre - just ask for "Boundary House") and Abingdon United football club.
If you walk up the Oxford Road from the town centre, it will take about 20 minutes to reach The Spread Eagle.
